Given are the results of research and development of wire for welding cold-resistant nickel steels with 6 and 9 % Ni, providing full-strength welded joints with high toughness and ductility values at a temperature of up to 77 K. It is shown that to ensure low-temperature toughness of the weld made using the Sv-OH12VI wire, it is necessary to create conditions for tempering of the weld metal after each pass, which is achieved by making stringer welds by the short- or immersed-arc multipass welding method.
Keywords: multipass welding, tempering, reheating, cold-resistant steels, welding consumables, ductile properties, full strength, deposition coefficient, heat input, residual austenite, low-temperature toughness
